KNOCK-DOWN DISPLAY BOX Filed Dec. 17, 1952 2 Sheets-Sheet 2 Jam/cs/ INVENTOR. Mwron LEV) United States Patent KNOGK-DOWN DISPLAY BOX Milton Levy, Woodr'nere, N. Y. Application December 17; 19 52; Sei'lal'Ni); 32638 8 Claims (Cl. 229-41) This invention relates to new and useful improvements in folding containers, cartons and boxes.

More particularly, the presentinventicn proposes the construction of a new and improved folding container, having two" interlocking base sections and a cover section, which can be stacked, shipped and stored as a flat blank of single thickness and which can be quickly and easily assembled into a container without thenecessity of any staples, string or additional fastening devices.

Another object of the present invention proposes forming the cover section or the folding container of flexible transparent plastic and't-he two base sections of stiff cardboard with die cut interlocking elements so that the entire unit may be made inexpensively and mass produced.

Still further, the present invention proposes constructing the foldable container with end members having finger openings for ease in raising and lowering and to permit free passage of air through the container.

As a further object, the present invention proposes arranging the two base sections of the new folding container in wedge shaped form with the end members or panels on the larger ends and providing the base sections with centrally opposed slots in their free sides so that the larger end of each base section may be superposed on the smaller end of the other wedge shaped base section, coacting tab locking elements being also provided to hold the base sections securely in such position.

The present invention further proposes a novel arrangement of a folding box which can be used as a display container, box or carton for packaging hair brushes, powder puffs, items of clothing, or food products such as bakery goods or produce.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a plan view of a blank for forming the folding container of the present invention.

Fig. 2 is a view similar to Fig. 1 but showing the two base sections folded under the center cover section.

Fig. 3 is a bottom view illustrating the method of folding and assembly of the container.

Fig. 4 is a perspective view of the container after assembly.

Fig. 5 is a sectional view taken on line 55 of Fig. 4.

Fig. 6 is a fragmentary enlarged sectional view taken on line 66 of Fig. 4.

Fig. 7 is a perspective view of two end pieces which may be inserted in the container on each side of the contents of the container to block the holes in the end members when this is desired.

Referring more particularly to the drawing, the new and improved container is composed of a blank 13 having two wedge shaped base sections 14 and 15 and a cover section 16. The base sections 14 and 15 have end panels 2 or members 17 and 18 respectively. End panel 17 is hinged to the larger end 19 of base section 14' and end panel 18 is hinged to-the larger end 20' of base section 15 Preferably the base sections 14 and 15 and the cover section16 are formed in three pieces as shown with the cover section 16 having one side portion 21 connected as by staples 22 toside' 23'of base section 14 and having its other side portion 24' connected as by staples 25 to side 26-of b'a'se section 15. The base sections 14 and 15' preferably are rrrade of stiff cardboard or fibreboard and the cover section 1 6 of transparent flexible thermoplastic sheeting. Sheeting of .005 to .020 gauge, inclusive, has been found particularly suitable for this pulposei- The base sections 14 and 15 may be die cut or stamped and joined by staples 22 and 25 01 wire stitches, eyelets, rivets, cement and other fastening devices, not shown) to the cover section 16. Side portions 21- and 24 of cover .section16', to which the sides 23 and 26 of basesections 14 and 15 are secured respectively, are bent under and parallel to the restof the cover sect-ion along crease lines 27 and 28, respectively. Crease lines 27' and 28 may easily be formed in thermoplastic sheeting by means of a heated blade. This may be done by the maker of the blank or by the assembler ofthe cont-ainer from the blank. or this step may be omitted if the material from which the cover section is formed is" flexible enoughto permit bending withoutinitial creasrn'g.

While end panels or members 1-7 and 1'8 maybe separate pieces hinged to the base sections, preferably they are formed integral with the base sections as shown. End panel 17 is simply an extension of base section 14 and end panel 18 an extension of base section 15. A score line 29 separates end panel 17 from the base section 14 and a score line 30 separates end panel 18 from base section 15. The fibrous nature of the cardboard or other similar material from which these parts are formed provides a hinge at each scoreline.

Each base section 14 and 15 has a cut 31 adjacent and parallel to its score line with cuts 32 and 33 at the end-s of cut 31. The cuts 32 and 33 extend across the scorelines to form together with the cut 31 locking tab openings 34 and 35 when the end members 17 and 18 are raised from the blank.

Base section 14 is provided with a lock-ing tab 36 at its smaller end 37 and base section 15 with a similar tab 38 at its smaller end 39.

End panels 17 and 18 have finger openings 40 extending through them for raising and lowering these end panels in forming, and opening and closing the container. In addition, finger holes or openings 40 serve as means to ventilate the container and permit free passage of air through it. The end panels 17 and 18 are shown of rounded cont-our but may be of any shape to provide a frame for the flexible cover section of any desired for-m.

Cover section 16 as shown is an oblong or rectangular thermoplastic sheet. A beaded or rolled edge 41 is formed on each end of the cover section, these ends being of a length to go around the free edges of the end panels.

The base sections 14 and 15 also have centrally opposed slots 42 and 43 in their free side edges 44 and 45 respectively for interhooking to dispose the larger end of each wedge shaped base section over the smaller end of the other wedge shaped base section in superposed relation. (See Figs. 3, 4 and 5.)

To assemble or set up a container from the blank 13, it is necessary only to draw the base sections 14 and 15 together and interhook the slots 42 and 43 with the larger end of each base section superposed on the smaller end of the other base section. The end panels 17 and 18 are then raised and by finger holes or openings 40 Patented-Aug. 21 1956' 3 pushed inside the cover section 16 and then pulled back until they abut the beaded edges 41 on the ends of the cover section 16.

Locking tabs 36 and 38 are the-n bent upwardly and inserted into the locking tab openings 34 and 35 to secure the container in assembled form. It Will be noted that the downwardly projecting member 46 below the bottorn edges of the end panels 17 and 18, formed by the cuts 31, 32 and 33 in the base members provides a guide and end abutment for the locking tabs.

While it will be desirable to have finger openings ill open for ventilating the container in many instances when such openings are not desired, insertion plates 43' and 44 (see Fig. 7) may be provided, one plate being inserted in each end or" the container between the product (not shown) in the container and the end panels 17 and 18. The cover section may be slightly precurved from one side to the other to aid in assembly.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
